INKWELL.

v Application filed January 9, 1924. serial No. 685,114.

This invention relates broadly to fluid dispensing receptacles, and more particularly to improvements in automatic attachments for dispensing Writing fluid or the like insufficient quantity to satisfy the deinands of the ordinary pen, and more especially this invention aims to provide an improved attachment which may be placedyin 'an ordinary ink well, or bottle, and

which, upon insertion of -a en, supplies sufficient ink thereto without flldoding.

lVhile this invention is described and illustrated for use as an attachment for the purpose of delivering writing fluid to a pen,

- proved fluid dispensing apparatus which may be in the form of an attachment for receptacles containing writ-ing fluid or the like; the provision of an improved fluid dispensing apparatus including fluid measuring means; the provision of an improved fluid dispensing apparatus including improved fluid ejecting means; the provision of improved fluid dispensing apparatus including improved fluid ejecting and measuring means; the provision of improved fluid dispensing apparatus which includes means for excluding dust; the provision of an improved fluid dispensing apparatus which includes improved means for pre.-

venting evaporation of the fluid; the pro.,- vision of improved fluid dispensing apparatus which includes means for preventing the filling of fountain pens therefrom; the provision of an improved vfluid dispensing device including fluid ejectingmeans which operates to dispense all of the contents of the container in which the deviceis placed, thus avoiding waste; thevprovision of an improved fluid dispensing apparatus in which the parts are so constructed that corrosion thereof can not take place;l and the provision of a device ofthe character described wliich is simple in construction,

readily disassembled for cleaning or repair, and-capable of manufacture at low cost.

The foregoing and such other objects and advantages which may appear or be pointed out as this description proceeds are attained in the structural embodiment illustrated in the accompanying drawing` in which:

Figure 1 is a side elevation view, partly in section of the device of this "invention placed in an ordinary ink container;

Figure 2 is a top plan view of the same;

and

Figure 3 is an elevational View of a detail. Referring more particularly to the drawing, 5 indicates generally a suitable container for writing fluid or the like, said container being provided with a neck 6, formed with an upper annular flange 7. Any other suitable container may be provided, if desired, and as will be pointed out y hereinafter, the device of this invention is readily adapted to various types of recep-V tacles. I

The fluid dispensing device of this invention, in the embodiment thereof illustrated herewith, includes a cylinder or sump 8 l which forms a pocket or container which is introduced into the receptacle 5, and supported thereby. A

The lower end of the cylinder 8 is internally threaded to receive a plug 9, and the upper end of the cylinder is internally threaded to receive the downwardly directed internal flange 10 of the cap member 11, the latter having afxternal annular flange 12 lying-externally of the neck 6 of the receptacle 5, and thus the cap member 11 forms the main support for the device in the receptacle '5.

The fluid ejecting means performs two functions; that is, it inducts fluid into the cylinder 8, and also expels this fluid.

The fluid ejecting means preferably comprises a piston or plunger 13 provided with an axialductv 14 and an outer substantially conical recess 15,` the duct 14 establishing communication between the bottom of the cylinder and said recess.

A substantially conical cup or receptacle 16 is mounted in the recess 15, and as best seen in Figure 3, said receptacle 16 is protheir upper ends, terminate in the discharge ports 18. 'When the receptacle 16 is placed in the recess 15 it will be observed that the grooves 17 which extend from the apex from said receptacle are placed in communication with the duct 14'. A

The plunger is lnormally maintained in the upper position by the provision of a helical spring 19 which is placed between the lower end of the plunger and the plug 9, and the cylinder 8 is provided with inlet ports 2O which afiord communication between the interior of the cylinder and the interior of the container 5.

It may be desirable that the duct 14: be slightly greater in dimension than the openings 2O in the cylinder so that the rise of the fluid through said duct will be assured, but this is not absolutely necessary.

When in operation, the plunger or piston 13 is depressed against the tension of the spring 19 the fluid contents of the cylinder below said piston are forced up through the duct 1s and due to the position of the cup 16 the fluid is deflected through the grooves 17 and out of the discharge ports 18 onto the pen which is inserted into said cup. In this way a direct passageway of the fluid to the cup is prevented so that dust can not enter into thedevice through the duct 14, and furthermore only suflicient ink will be delivered to the cup for wetting the pen, thus preventing filling of fountain pens and the like from the ink weil.

It will be observed from an inspection of. Figure 1 that the upward movement of the plunger and cup is limited by the shoulder afforded by the tlange 10, and thus the device forms a complete unit in itself which may be l"placed in any suitable container. The dimensions of the cap member 11 may be varied, that is, the flange 12 may be formed at a greater distance from the flange 10 than,

that shown so as to accommodate various sizes of receptacles. It will be observed that due to the position of the lower end of the cylinder in the receptacle 5, all of the fluid contents will be dispensed and no waste will result.

It will be understood that after a depression of the plunger it is returned by the spring 19, and upon such return, an additional increment of fluid is drawn into the cylinder preparatory to a further dispensing of such fluid.

4We claim:

1. In a device of the character-described, a cylinder, a plunger operable in said cylinder and provided with a central duct and an outer conical socket, and a receptacle mounted in said socket having passageways formed on its inner surface terminating in apertures communicating with said duct.

2. In a device of the character described, a cylinder, a plunger operable in said cylinder and provided with a central duct and an outer socket, said cylinder having inlet ports, and a receptacle in said socket having a passageway communicating with said duct and extending along the side of said socket.

In a device of the character described, in combination, a cylinder having inlet ports, a supporting flange on said cylinder, a plunger operable in the cylinder and provided with a central duct and a substantially conical endrecess, and a receptacle supported in said recess and provided with a passageway communicating with said duct and the interior of said receptacle.

4. In a device of the character described, in combination, a cylinder having inlet ports, a supporting flange on said cylinder, a plunger operable in the cylinder and provided with a central duct and a substantially conical end recess, said flange serving also to limit movement of the plunger in one direction, and a receptacle supported in said recess and provided with a passageway communicating with said duct and the interior ofi' said receptacle.

5. In a device of' the character described, in combination, a pocket container for fluid, a cup supported within said pocket container, and a passageway for fluid from the latterl to and entering said cup only at its sides.

G. In a device of the character described, in combination, a pocket container for fluid, a conical cup supported within said pocket container, and movable relatively thereto, and a passageway for fluid between said container and cup entering the cup above its apex.

7. In a device of the character described, in combination, a pocket container for fluid, an auxiliary cup container supported within said first mentioned container, and movable relatively thereto, and a passageway for 'fluid betwen said containers entering the auxiliary cup container above its bottoni, relative movement of said containers causing fluid to flow through said passageway.

In testimony whereof we affix our signatures at Majestic Building, Detroit, Michiffan.
